There is a relatively new motor scooter rental place across from Havensight (where the cruise ships come in). The manager has been quoted as saying you have to have experience driving one for him to rent, however I have seen tourists driving up sidewalks and careening down streets, so I guess that rule might not get followed. Do you have good health insurance that includes "Life Flight" to Puerto Rico? There is no neurosurgeon on island and that is where they would send you...
